  • Hi Repetier... I'm not sure what happened to the OP but I am interested in the same thing. Some of the more interesting developments in cnc seem to be around the 5 axis machine and making it affordable. The benefits can easily be seen in this link: …

  • Ok thanks RAyWB... In the mean time I'm going to take your code and play around with it a bit to see if I can get some of this to work... from what I've read the Due and 2560 are similar in coding just different pin assignments and such... but I'm n…

  • I think I want to do exactly what you are doing. I'd like to be able to use the printer manually or automatically. in manual mode, I'd use the joystick to manoeuvre the print platform to specific locations or laser weld a part manually. I read that …

  • Hi RAyWB... Im using a ramps 1.4 board with a mega 2560... and ive got two arduino joysticks and a 4x4 keypad... all of the stuff ive got are chinese knock offs. Keypad: 4 x 4 AVR 16 Key Matrix Array membrane Joystick: biaxial XY Joystick Module KY…

  • Hi RAyWB... i have been wanting to do this for a while now. Im only a beginner with code so can you provide more detail and/or pics/schematics to help me understand where to wire the joystick and the keypad? Im using a ramps 1.4 board with a mega 25…

  • Thanks Repetier. Ill check it out and let you know what i find.
    in How to set a LASER PULSE Comment by robgs May 2016
  • Hi Repetier. Thanks for the hint. Ill look in that section to set the pwm. Ive been reading up on the PWM and the lowest frequency it can be set to. Setting the devisor (prescaler) to 1024 should give me < 30Hz... does that sound right? Can i var…

  • Hey. Good news. It turns out the code i wrote above works just fine. As i was trying different code to set my "while" loop, i started looking at the setup of slic3r. The pre print code was setting the fan to 255 as soon as the printer started its mo…

  • Hi RAyWB. I just looked that up. Yes im sure i can add more to my setup but id like to try it without adding any extra components if i dont have to. . It just seems more simple to add a "blink" to the existing code. But im no expert.

  • Hi Repetier. Yes. I downloaded the avr data sheet. Its pretty complex so it will take me some time to understand. i'll work on that solution last as i dont want to mess my current settings until im comfortable i know what im doing. You're absolutely…

  • Hi Repetier. i really like that idea because it would accomplish exactly what i need. My laser has a max pulse output of 1 kHz and even at that i think it would go through bulbs like crazy. Its a flash lamp pumped nd yag and the bulbs are $360 US so…

  • Just looking at the schematic and from what i see posted, p44 is a digital PWM pin so modulating can be done there. Its an interesting concept which could work if i can get very low frequencies like 2 or 3 Hz. Im going to have to read up on PWM and…

  • Hi RepRoland. Yes. Ive been contemplating that solution as well (using a seperate board or card) but i will have other uses for the pulse that need to coincide with the laser firing... and yes im sure i can still accomplish this with more IO but id …
    in How to set a LASER PULSE Comment by robgs April 2016
  • Hello Repetier and thank you for the reply. Yes. Through trial and error i did find that code (as im just learning c++). I noticed that alternating uint8_t LaserDriver::intensity = between 255 and 0 does turn the laser on and off which is fine …

  • Hi Repetier support. Sorry it took so long but the problem corrected itself! I changed the PRINTLINE_CACHE_SIZE back to 16 from 5 (i changed it to troubleshoot) to try to get the code, but after i did... the problem was gone. Starts at layer 1 ever…
    in Skipping first 4 lines of print HELP Comment by robgs March 2016
  • Hello. Thanks for the quick response. Im not sure i can explain it better than i did. I'll try. My printer is skipping the first 4 layers. It starts "trying" to print layer number 5 which is too far away from the bed. Repetier preview instantly sh…
    in Skipping first 4 lines of print HELP Comment by robgs March 2016
  • *Update*Just pissing around I noticed PRINTLINE_CACHE_SIZE which is set to 16 (which is probably the lines of code in the buffer). Following it around I noticed there were some optimizations and that the lowest this number can be is 5. So I set it t…
